Abstract

A disc cartridge assembling apparatus in which a protuberance formed on the inner surface of one of cartridge halves of a thermoplastic resin making up a main cartridge body unit is passed through a through-hole formed in the other cartridge half in register with the protuberance, and in which the distal end of the protuberance is thermally deformed to interconnect the cartridge halves. The upper and lower cartridge halves are stacked together, with a protuberance formed on the upper cartridge half being passed through the through-hole formed in the upper cartridge half, and are held by a holding mechanism. In this state, the distal end of the protuberance is thermally deformed by a caulking head, heated by a heater, and which is provided with a recess in its surface adapted to compress against the protuberance. Then, as the caulking head is moved away from the thermally deformed protuberance, the caulking head and the protuberance are cooled by a cooling mechanism. This effectively shortens the caulking process since the thermal deformation of the protuberance until the solidification.
